KNITTING-IVIACI-IINE.

To all whom, t may concern 1 Be it known that I, MAX NYDEGGER, a citizen of Switzerland, and'resident of the city of Elizabeth, county ofUnionfand State of New Jersey, have invented an Improvement.

in Knitting-Machines, of which thefollowling description, in connection with the accompanyingdrawings, isa specification, like letters on'the drawings represent-ing like parts. "I l y The present invention relates to an improvement in knitting machines of theY straight bed type, and particularly to that class of machines commonly used inknitting sweaters or garments ofy similar texture. i

The object of the invention is to provide a machine with which it ispossible to knit the body. andA pockets of a sweateror knit-- ted garmentin a continuous operation.

It has heretofore been the custom, in making garments of the kind referred to, vto knit the body and pocket portions separately and afterward to sew or splice the pocket into the fabric of the body of the garment. By the use of my improvement, the pocket may be knittedv in at its proper place in the course of knitting. the whole garment without removing the fabricfrom the machine and without interrupting the continuity of the knitting. It will be ob` vious that such improvement` will serve to reduce materially the amount of hand labo-r.

on knitted sweaters andthe like and obviate the necessity for having an extra machine to make the pocket portions.

Inasmuch as the improvements consist of a modification in the structure and arrangement of needles and simple additional mechanism in the cam boX,-they may be incorporated in existing machines of the straight bed type at very little inconvenience andl expense.

One practical embodiment of my invens tion is shown in the accompanying draw-` ings, in which,

Y Figure 1 is a front elevation of the needle plate with complement of needles, Fig. 2 is a detail plan view of a cam box, and Figs.

3 and 4 are longitudinal and cross sections` on the lines 3 3 and 4-4 respectively of,

Fig. 2.

may be actuated while the other needle remains inoperative. For this purpose I prefer to equip a portion'ofthe needle plate 1 with needles 2 having high butts 5 while the remaining needles 3 are the ordinary or low butt needles. l

In normal operation the cam box 4 re` Y ciprocates back and forth across the-needle plate V1, engaging, by means of cams 6 and l7,.the butts of ally the needles. These cams andthe well known mechanism which causes or lock plate 8 which is itself adapted to be raised and lowered.' Attached to the cam plate, are plungers 9 and 10 provided with slots -11 and 12. respectively, having both horizontal and inclined bearing surfaces.

A slidable bar 13, suitably mounted in the cam box, engagesv these slots 11 and 12 in the plungers. AsV shown in Fig. 3, the cam plate is in normal or lowposition with the cam box moving in the direction of the ar-` row. In order to shift the cam plate and cams to a higher position, the'bar 13 is pulled in the direction of the arrow by means of a handle 14, thus causing the inthem alternately to engage and pass over Y the needle butts are mounted on al cam plate clined faces 15 of the bar 13 to bear up-` wardly against the undercut faces 16 in the plungers and consequently to raise the plungers so that a horizontal partl of the bar will bear against the horizontal surfaces .o-f the slots in the plungers and hold the latter securely yin their resulting -raised position, wherein only the high butt needles will be engaged by the cams in their course across the needle plate. In a similaimanner, a third positionof the cam platemay be effected by providing another incline and raised portion in the bar. In this highest position, the cam box may be'made to travf erse the needle plate without operating any kof the needles.

I claim as myinvention:-

1. In a knitting machine, the combinatio-n with acam box having a cam plate movable relatively thereto, of plungerrods attached to the said cam plate, and a bar in slidable engagement with the said plunger rods to eEect the raising and lowering of the cam plate. y v

2.l In a knitting machine, the combination with a cam box having a cam plate movable relatively thereto, of plunger rods attached to the said cam'plate and having slots in the sides, and a bar having inclinedfaces adapted to slide in the said slots. Y

3. In a straight knitting machine, the combination with a cam boX, of a cam plate adapted to be moved vertically in the cam box, and means to effect the said vertical movement and secure the cam plate in operative position.

4. In a knitting machine, the combination With a cam box, of a cam plate adapted to be moved vertically in `the cam box, plunbar' adapted to engage the said plungers and to Secure them in operative position.

5, In a knitting machine, the combination with a cam boX, of a cam plate adapted t0 be moved vertically in the cam box, plungers mounted upon the lock vplate and havA copis of this patent may be obtained for ing slots in their sides, and a bar having alternating horizontal vand inclined portions adapted to slidein the said slots.

6. Ina knitting machine, the combination with a camY box, of a cam plate carried by plungers having slots in their sides, each of the said `slots being formed to provide up- Wardly exposed inclined and horizontal bearing' Surfaces and downwardly exposed horizontal and inclined bearing surfaces,

y'and a bar adapted to engage the'said Slots. gers mounted uponv the cam plate, and aV In'testilnony whereof, I have Signed my name to this specification, in the presence of two subscribing Witnesses. i y
